The game uses a third-person exploration view with a cursor-based interface. Move Graham through screens, inspect scenery, talk to characters, collect objects, and combine or use inventory items to solve puzzles.

Progression follows a largely linear chain of locations, with some opportunities to revisit areas. Correct item use and careful observation are essential, while several choices can cause an unwinnable situation or sudden death. The NES version also includes short action-oriented passages and timing challenges.

Save frequently, especially before entering unfamiliar screens or attempting a puzzle. Examine every object and speak with helpful characters before leaving an area.

Keep seemingly minor items. Several solutions depend on using an object before its purpose is obvious, and some scenes can become impossible if a required item is missed or used incorrectly.

• Test actions cautiously around dangerous creatures and traps.
• Revisit earlier locations when a new item or clue changes their possible uses.
